Paytools
Para desarrolladores
Gratis
Paytools is an offline payment-engineering workbench for developers, QA engineers, integrators, students, and fintech teams.
Decode and inspect common payment-message structures, explore field definitions, convert technical data, and keep essential payment references close at hand. Processing happens locally on your device, so pasted messages and imported files are not uploaded to a server.
PAYMENT TOOLS
• Inspect ISO 8583 MTIs, bitmaps, and present data elements
• Decode and build primary and secondary bitmaps
• Parse BER-TLV data and identify common EMV tags
• Recognize SWIFT MT blocks and ISO 20022 XML messages
• Convert between HEX, ASCII, decimal, binary, and packed BCD
• Validate synthetic card numbers with the Luhn algorithm
• Compose synthetic Track 2 and ISO-0 PIN-block test data
• Use development utilities for XOR and DES odd parity
KNOWLEDGE LIBRARY
• Search all 128 ISO 8583 data elements
• Learn ISO 8583:1987, 1993, and 2003 MTI concepts
• Follow authorization from merchant to acquirer, scheme, and issuer
• Understand STIP, advice, reversal, clearing, and settlement flows
• Review ISO 20022 message families and validation concepts
• Study EMV transaction and cryptogram terminology
CODES AND FIELDS
Search operational response-code references for common ISO profiles, Visa, Mastercard, UnionPay/UPI, 3-D Secure, and gateway HTTP outcomes. Open any ISO field for its purpose, format, and implementation notes, including an expanded guide to DE22 POS Entry Mode.
PRIVATE BY DESIGN
Paytools has no account requirement and no cloud processing. Use synthetic or appropriately masked test data. Production payment formats and code meanings can vary by network, region, product, and specification release.
Paytools is an independent educational and development utility. It is not affiliated with or endorsed by any payment network. Formal certification and production processing require the current authorized specifications, test packs, approved cryptographic systems, and applicable security controls.
